To'allwhom' it may concern Be it known that I, VICTOR L. RoBnR'rsoN,

a citizeno'f the Unit'eclStates', and af resident of the city of Rexburg', county of Madison,

and State ofldaho, have invented certain new and useful Improvements in Automobile:EXti'-actors,"of which the following is v a specification.

My invention relates? to improvements in automobile extractors in general, and more particularlyto that type of extractors employing a cable or other flexible element wrapping on adruin driven by theautomobile motor. J

A principalobject of the invention is to provide a device that is easily portable'with in the body of thevehicle. A further ob ject. is to" provide adevice. that may be readily applied to almost any make orsize a of vehicle. A further object is to provide a device composed ofa'plurality ofessentially similar elements which" may be readily assembled for use and disassembled and closely packed or nested for transportation,

and a further object is to provide a device of great simplicity and manufacturing economy.

With'these and other objectsin view my invention relates to the general construction and details illustrated in the accompanying drawings, it being understood that I claim such modifications of the device and of its application as come within the spirit of the appended claims.

In the drawings :Figure' 1 illustrates an assembled elevation of the device on a fragmentary portion of a vehicle wheel the spokes of fwhich are indicated by broken lines. Fig.2 is a partial, sectional plan view taken on line 22 of Fig. 1. Fig. 3 is a view before same is bent or formed. Fig. 4 is a side elevation of one of the elements. Flg.

5 is a modified sectional elevation on line 5'5 of Fig. 4, and Fig. 6 is a plan view of the device as modified in Fig. 5.

In the drawings the numerals 7 indicates in general one of the elements of which the device is composed consisting of the body or shank-8 and the enlarged head 9 which is split laterally for a portion of its width, as at 10. and longitudinally for a portion of its length, as at 11, forming a plurality of lobes 12 .on the outer portion of the head and a plurality of lobes 13 on the inner portion Specification of Letters Patent. v Application filed January 6, i919. seriarnog' aeaeaa element on line. 17, flanges 1 1,

connected a flanged. portion 1 1' formed byben'ding' or' 5 folding the head on being connected by a flanged portion 15 integralwith body 8 formed by bending the line'16, and lobes'13' and 15 being interconnected by'the' medial portion 18 of V head 9.

Thefshank ory bo'dy'elenient '8 is formed arcuatelyas a't-19 and folded .backwardly as at 20 so the'lower portion of the shank 215s essentially parallel to flanges'll and 15, the

slot 22 to'rec'eive bolt 23. Thenumeral 2ft indicatesthe hub of; are'ar wheel of a motor vehicle with 'i tsprojection" or cap 25 and plurality of. radial spokes 26, 27 indicating a brake drum customarily attached to the rear wheel ofthe vehicle. 7

In operation a-pluralityof elements 7 are arranged. radially around thewheel hub s0 that the lobes 12-and flange '14 are on the inner side of the radial spokes 26, the medial portion 18' lying between adjacent spokes 26 and lobes 13-and flange 15 contacting with the outer'port'ion of said spokes and hub and are so arranged that the slots 22 in the various elements are assembled on bolt 23 which passes through the slots of all the various elements 7. These elements may be mounted betweenall the spokes of the wheel or-between a portion of them only at the volition of the operator. When so assembled the arcuate portions 19 compose a drum sur-' rounding the wheel hub or cap upon which a rope, cable, chain orother flexible element erably in advance of said motor vehicle. of one of the elements composing the device As the rear Wheels of said vehicle are re volved under the action of the vehicle motor perforated by an elongated Yes the flexible element will be wound or" I wrapped around said drum composed of ole-- rooms 19 and so cause the vehicle to be impelled forwardly regardless of the slippage that may oc"ur between the tread of said wheels and the ground upon which they rest. It is understood that the arcuate portions 19 may be curved or embossed as shown at 19 to produce a more nearly circular wrapping drum for said flexible element,-if so desired. Thecable or flexibleelemei'it is not shown in the drawings as it, as such, formsno portion of this invention and may automobile extractor composed of a plurality of essentially similar elements, each element being formed from a single piece of material, and having one end thereof 1nou11ted between adjacent spokes of a 'Vehicle wheel, the other extremity of said elements being adjustably inter-connected beyond the hub of said wheel, by a single fastening membenthe medial portions of said ele-' ments forming essentially a drumsurrounding said hub.

2. In an automobile extractor the oombination with a vehicle wheel, of a plurality of essentially similar elements so shaped and mounted on said wheel as to form essentially a drum surrounding said wheel hub, one extremity of each of said elements being enlarged and provided with flanges to engage adjacent spokes of said wheel, the; other extremity of said elements being mutually in-' ter-conneoted by a single fastening member beyond the extremity of said hub.

3. In an automobile extractor in combination with an automobile wheel and'hub, a drum surrounding said hub, said drum" being composed of a plurality of essentially similar elements,- each element having one endthereof mounted between the spokes of said Wheel, an elongated slot near the outer extremity of each of said elements, the outer extremity of said elements being mutually inter-secured by a'bolt passing through said slot in each of said elements, each of said elements being composed of a single piece of material bent to a'required configuration essentially as, and for thepurpose described. 4. An automobile extractor comprised of a" plurality of elements each element being formed from a singlesheet of metal, said elements'each comprising a body or shank,

a head integral with said body, said head being out to form a plurality of lobes and alined flanges connected by a medial member, said body being bent for a portion of its length in arcuate form, the outer extremlty of said body being bent into essential parallelism with said lobes and flanges and provided with a slot or opening for the reception of a clamping member.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
